There were deliveries from 3 different railroads depending on which builder was used for certain models The Lehigh Valley, The Lackawanna ( Later Erie Lackawanna) and the New York Central. Here are some pics of deliveries via Bush Terminal in Brooklyn. There were a few options of getting them onto TA tracks. My favorite spot to watch this was the interchange at Ave I and McDonald with the LIRR Bay Ridge branch
This is the 207th st yard car float
